Watashi no Oniichan

A series of “bishōjo”-centered manga booklets that were released weekly for a short time in Japan.

The manga would come packaged with a limited edition plastic-figure assembly kit, designed by Ohshima Yuki, of the featured character of the week:
Volume 1 – New! – Figure for volume 1 – Mion
Volume 2 – Two! – Figure for volume 2 – Ashita
Volume 3 – Hot! – Figure for volume 3 – Harusame
Volume 4 – Why!? – Figure for volume 4 – Sonome
Volume 5 – Bye! – Figure for volume 5 – Eruron
Bonus volume – eXtra! – Figure for bonus volume – Tetora

There is a conspicuous absence of the brothers (oniichan) of the title, as only the little girls are ‘portrayed.
